CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 272,508, dated February 20, 1883.

Application filed December 22, 1882. (No model.)

To all whom it may concern Be it known that I, ROBERT ZEPPENFIELD, of St. Louis, Missouri, have made a new and useful Improvement in Railway-OarOil-Boxes, of which the following is a full, clear, and ex: act'description, reference being had to the annexed-drawings,making partof this specification, in which- Figure l is a longitudinal section taken through the improved box; Fig. 2, an elevation of the inner end of the box, the follower used to confine thepacking being removed; Fig. 3, an elevation from the inner side of the lower.

The same letters denote the same parts.

The present invention relates to the mode of packing the box at its inner end.

A, Figs. 1 and 2, represents the oil-box of a railway-car axle. Saving theimprovement in question, the box is of the usual description.

B represents the car-axle, and O the journalbox, also of the customary form. The car-axle and oil-box are also relatively arranged in the ordinary manner. In place, however, of the usual guard-plates upon the shoulder 12 of the ax'le a packing-strip, D, preferably in the form of what is termed square packing, is used. This packing-strip serves to keep the dirt, grit, and dust from entering the oil-box, but more especially to prevent the oil from escaping from the box. To this end the packing-strip is wrapped around the axle, substantially as shown, and its ends d 01 extended outward therefrom and connected with-devices suited for drawing, or for enabling the ends 01 d to be drawn, and the packing thereby tightened around the axle. g

A convenient form of tightening device is that shown, the ends d d of the packing-strip, by means of the links 0 6, being connected with the headsfor nuts 6 0 the washers e e, and the springs'e 6 The washers e c bear upon the oil-box, and the springs at one end bear upon the washers e e and at the other end against the washers 8 e and act to lift the bolts and draw the packing around the axle. to continue for a considerable period to tighten the packing as it wears away or stretches, and by tightening the nuts c 0 upon the bolts the springs can be readjusted. The springs might be made to bear directly upon the oil-box and against the heads or nuts 0 e'. The oil-box is suitably shaped or perforated, as at a a, to pro vide for connecting the packingstrip and bolts 6 c. I

To prevent the dirt or oil from passing the outer side of the packing, the latter is pressed laterally against a shoulder or flange, a, with which the oil-box is provided. The lateral pressure upon the packing is obtained by means of the follower F, the follower being drawn against thc packing by means of the bolts ff, which connect with the oil-box.

To enable the follower to bear all around against the packing, it is furnished with a projection,f, which comes against that portion of the packing-coil which lies farther within the oil-box. The flange a may have a similar projection for a similar purpose.

The present improvement is advantageous, not only in that thereby the oil-box is very effectually packed, but also in that it enables the waste commonly used in oil-boxes to be dispensed with and oil, G, only to he'introduced into the oil-box.

I claima 1. The combination of the oil-box A, the caraxle B, the packing D, the bolts e e, the nuts 6 c and the springs e 0 substantially as described.

2; The combination of the oil-box A, the car axle B, the packing D, and the follower F,substantially as described.

3'. The combination of the oil-box A, the caraxle B, the packing D, the tightening device 6 e e e e c ,and the-follower F, substantially as described. 7

The springs are under sufficient tension.
